A magnetic separator comprising a conveyor system configured to drive a conveyor element in a running direction, and a cooperating magnetic component arranged in proximity to the conveyor element. The magnetic component comprises a magnetic body having rows of magnets oriented transversely relative to a longitudinal axis of the magnetic component, the longitudinal axis being aligned generally parallel to the running direction of the conveyor element. The polar axis of each magnet is aligned generally parallel to the longitudinal axis and consecutive rows of the magnets are arranged so that like magnetic poles of the magnets face and repel each other to establish zones of alternating magnetic polarity. Elongate separator plates may be sandwiched between consecutive rows of the magnets. Also provided is a method for separating magnetically susceptible particulates from a mixture using the separator. The mixture may, for example, comprise Run-of-the-Mine, crushed ore, mining waste or slag.
